JOHN S. MUGG, OF GOODLAND, INDIANA.

DOUBLE SAFETY SNAP-HOOK.

SPECIFICATION formingpart of Letters Patent No. 720,050, dated February 10, 1903.

Application filed March 31,1902. Serial No. 100,783. (No model) To all whom) it may concern:

Be it known that I, JOHN S. MUGG, a citizen of the United States, residing at Goodland, in the county of Newton and State of Indiana, have invented a new and useful Double Safety Snap-Hook, of which the following is a specification.

This invention relates to double safety snaphooks for harness.

The object of the invention is to provide a snap-hook of the above character which shall be simple of construction, thoroughly efficient and durable in use, cheap of manufacture, and readily operable in being attached to and detached from the part with which it coacts.

With these and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the novel construction and combination of parts of a double safety snap-hook, as will behereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which like numerals of reference indicate corresponding parts, there is illustrated one form of embodiment of the invention capable of carrying the same into practical operation, it being understood that the elements therein exhibited may be varied or changed as to shape, proportion, and exact manner of assemblage without departing from the scope of the invention, and in these drawings Figure 1 is a view in perspective of a snaphook constructed in accordance with the present invention. Fig. 2 is a view in longitudinal section. Fig. 3 is a view in transverse section.

Referring to the drawings, 1 designates the shank of the hook provided with the usual attaching-loop 2, 3 a latch-bolt provided with a head 4, and 5 the two hooks, which latter may be associated with the shank invany preferred manner, preferably by being cast integral therewith. The hooks have their terminals 6 disposed on opposite sides of the shank and in parallelism with the attaching-loop and are engaged by the head 4, so that when in engagement with a ring or other object it will be held against accidental separation from the loops formed between the head and the bends of the hooks. As herein shown, the head is approximately diamond-shaped in order that its projecting sides may be readily'grasped when the latch-bolt is to be retracted to free the ring from engagement with thehooks; but it is to be understood that the head may be of other shape than that shown-and still be within the scope of the invention. The latch-bolt is guided for proper cooperative engagement with the terminals of the hook by a feather or spline 7, which engages a keyway 8, formed in the inner wall of the shank, andis held normally projected by a coiled spring 9, housed in the shank and bearing against the inner end of the latch-bolt. By thus positively covering the ends of the hook 6 all danger of their catching on objects will be obviated, and by the provision of the double hook disposed in the manner described'when a ring is once associated therewith it will be securely held from. accidental separation therefrom, and

even though the ring should by any means work loose in one of the hooks the chances are that it will be retained by the other hook, and thereby cause the snap-hook to perform the function for which it is designed.

Instead of retracting the latch-bolt by grasping its head with the fingers, as described, separation of the hooks from the ring may be effected by pressing the head against the ring, thus to clear it of the terminals of the hooks 5, and giving a quarter-turn to the shank, when the ring will be freed.

The safety-hook of this invention is exceedingly simple of construction and will be found thoroughly efficient and durable in use and may be relied upon for performing the functions for which it is designed in a positive and satisfactory manner.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A double safety snap-hook, comprising a tubular shank, hooks disposed on opposite sides of the shank and parallel therewith and having their terminals disposed toward the rear thereof, and a spring-pressed latch-bolt having a head normally engaging the hookterminals, and projecting laterally beyond the same to present finger-holds.

A double safety snap hook, comprising guiding the head into engagement with the [O a tubular shank, hooks disposed on opposite terminals. sides of the shanks and parallel therewith In testimony that I claim the foregoing as and having their terminals disposed toward my own I have hereto affixed my signature in the rear thereof, a spring-pressed latch-bolt the presence of two witnesses. carried by the shank and having ahead nor- JOHN S. MUGG.
